Southern Fujian oolong was 'unfurled' until recently, I think. Does
anyone know when it switched?

Hi Alex,

You are right. Fujian Anxi only started to use the machine to roll the
leaves in early-mid 90's. Prior to that the Anxi oolong (tie guan yin,
se zhong, huang jin gui) looked very much like Wuyi Oolong and were
more heavely baked.

The machine was created in Taiwan and so rolled taiwanese oolongs were
available in the west prior to the early-mid 90's.
